I emailed them earlier and this was the response I got:
Hello,
I’m sorry for the inconvenience caused.
Whenever you pre-order a book, CD, video, DVD, software, or video game, the price we charge when we ship it to you will be the lowest price offered by Amazon.com between the time you placed your order and the release date.
If the price changes before the item ships, you'll see the updated price in Your Account. If the price changes after your shipment is already being prepared, you'll receive a refund within 24 - 48 hours of the release date.
